First aspect

The embodiment of the present application provides a head-mounted device 10, and referring to fig. 1 to 6, the head-mounted device 10 includes: the glasses comprise a wearing part 110, a sliding component 120 and a rotating component 130, wherein the wearing part 110 is provided with a wearing through hole 111, the sliding component 120 is connected with a first end 112 of the wearing part 110, a sliding part 121 of the sliding component 120 can slide towards a direction close to or far away from the first end 112, the rotating component 130 is connected with the sliding part 121, the rotating component 130 can rotate relative to the sliding part 121, and the rotating component 130 can be connected with glasses 140.

Specifically, the wearing portion 110 is provided with a wearing hole 111, and the wearing hole 111 can sleeve the wearing portion 110 on a helmet or a head of a user. The second end 113 of the wearing portion 110 may be opened with a notch communicating with the wearing hole 111, and the second end 113 of the wearing portion 110 and the first end 112 of the wearing portion 110 are opposite to each other, so that the wearing hole 111 is a through hole with a notch, whereby when the wearing portion 110 is worn on a helmet or a user's head having a circumferential dimension larger than the diameter of the wearing hole 111, the wearing portion 110 can be slightly deformed to increase the diameter of the wearing hole 111, thereby being suitable for a helmet or a user's head having a circumferential dimension larger than the diameter of the wearing hole 111, and the material for the wearing portion 110 can be reduced by providing the notch, thereby reducing the manufacturing cost of the wearing portion 110.

Among the above, the sliding unit 120 is connected to the first end 112 of the wearing unit 110, the sliding unit 121 of the sliding unit 120 is slidable in a direction approaching or separating from the first end 112, the rotating unit 130 is connected to the sliding unit 121, the rotating unit 130 is rotatable relative to the sliding unit 121, and the rotating unit 130 is connectable to the glasses 140, so that when the wearing unit 110 is worn on the head of the user, the first end 112 of the wearing unit 110 corresponds to the face of the user, and when the sliding unit 121 is slid in a direction approaching or separating from the first end 112, the distance between the glasses 140 and the eyes of the user can be changed, thereby adjusting the focal length and reducing interference between the glasses 140 and the glasses structure such as the myopia glasses worn by the user, and the angle of the glasses 140 can be adjusted when the rotating unit 130 to which the glasses 140 are connected rotates relative to the sliding unit 121. The rotating assembly 130 may be provided with a connecting structure such as a clamping portion and a clamping portion for connecting the glasses 140, and is not limited in detail here.

One method of use is: referring to fig. 8 to 23, the head-mounted device 10 is sleeved on the helmet 20 through the wearing through hole 111, when the helmet 20 is worn on the head of the user, the glasses 140 connected to the rotating assembly 130 are located in front of the eyes of the user, the user can move the sliding portion 121 as needed to adjust the distance between the eyes of the user and the glasses 140, and when the user does not use the glasses 140 for a while, the glasses 140 can be rotated to a position not to be applied to the eyes of the user by rotating the rotating assembly 130 relative to the sliding portion 121.

The other using method is as follows: when the head-mounted device 10 is sleeved on the head of the user through the wearing through hole 111, the glasses 140 connected to the rotating assembly 130 are located in front of the eyes of the user, the user can move the sliding portion 121 as required to adjust the distance between the eyes of the user and the glasses 140, and when the user does not use the glasses 140 temporarily, the glasses 140 can be rotated to a position where the eyes of the user are not applied by the rotation of the rotating assembly 130 relative to the sliding portion 121.

In this embodiment, the sliding component can move the eyeglasses towards the direction close to or away from the eyes, and the rotating component can rotate the eyeglasses, so that the problem of poor adjustability of the eyeglasses on the head-mounted device can be solved, and the application range of the head-mounted device can be expanded.
